I had a through the wall AC unit that needed to be replaced.  Because it was an older unit going through a brick wall it was going to cost almost $2000 to replace.  Nope!!!  I got this unit to go in the only window it would work in the family room which is a large odd shaped room.  In my honest opinion, i am finding this unit to be more efficient cooling down the room.  Not only that but it is significantly quieter than the older unit.  The last month has been incredibly humid on Long Island and I only drained the unit 1 time and not because I had to, but because i was curious how much water was collected and or returned into the environment.  Not much water at all!  Overall i am very pleased with how this unit cools.
